Vehicle and vehicle coupling lock control method and system

Abstract

Provided is a coupling lock control system for a vehicle. The vehicle has a plurality of wheels, the plurality of wheels are configured as at least one set of wheel pairs, and each set of wheel pairs comprises a first wheel (11a) and a second wheel (11b) connected to the same coupling lock (10). After a locking instruction for the coupling lock (10) is obtained, the wheel speeds of the first wheel (11a) and the second wheel (11b) connected to the same coupling lock (10) are obtained. Based on the difference between the wheel speeds of the first wheel (11a) and the second wheel (11b), the difference between the wheel speeds of the two wheels is obtained; based on the ratio of the greater value to the lower value of the wheel speeds of the first wheel (11a) and the second wheel (11b), the ratio of the wheel speeds of the two wheels is obtained; and the locking control of the coupling lock (10) is performed based on the difference between and the ratio of the wheel speeds of the two wheels, thereby enabling the coupling lock to lock quickly and safely, and preventing gear collisions and excessive wear. Further provided is a coupling lock control method for a vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle coupling lock control method, a vehicle coupling lock control system and a vehicle with the system. Background technique [0002] The related art discloses a differential lock control method and system, the system includes a differential lock switch, a central controller and a differential lock electromagnetic valve; The speed lock solenoid valve outputs the control signal; the differential lock solenoid valve is used to drive or prohibit the differential lock operation according to the control signal output by the central controller, so that the automatic control of the differential lock can be realized and the human factors can be avoided. Differential lock rattle problem. [0003] However, the existing problem is that the four-wheel speed cannot be actively controlled, which is a negative control method, and cannot quickly meet the driver's demand for locking the d...

Problems solved by technology

[0003] However, the existing problem is that the four-wheel speed cannot be actively controlled, and it is a passive control method, which cannot quickly meet the driver's demand for locking the differential lock while avoiding gear grinding.
